The Stand Caddy will hold your gear while in transport from the truck or van and can be lifted off with the equipment securely contained when you use the dolly as a shooting platform. The Stand Caddy is equipped with large rubber feet to protect the floor and can mount either inboard or outboard of the platform without exceeding the 29" width of the Doorway Dolly. When mounted outboard make sure there is enough other gear on the opposite end of the Doorway Dolly platform to counterbalance the weight. The Stand Caddy will accommodate Scrims and Flags up to 24x36 with plenty of room for C-Stands and other lighting stands. The Stand Caddy is the cleanest, safest and most efficient way of maximizing the versatility of your Matthews Doorway or Round-d-Round Doorway Dolly.
